Linkage Mapper uses GIS maps of core habitat areas and resistances to identify and map linkages between core areas. Each cell in a resistance map is attributed with a value reflecting the energetic cost, difficulty, or mortality risk of moving across that cell. Resistance values are typically determined by cell characteristics, such as land cover or housing density, combined with species-specific landscape resistance models. As animals move away from specific core areas, cost-weighted distance analyses produce maps of total movement resistance accumulated.The tool identifies adjacent (neighboring) core areas and create maps of least-cost corridors between them. It then mosaics the individual corridors to create...

The HCA toolkit is a GIS tool designed to support regional wildlife habitat connectivity analyses by automating the process of identifying habitat concentration areas (HCAs). HCAs are areas on the landscape between which patterns of connectivity are evaluated. The habitat areas identified by this toolkit may be used as an input for Linkage Mapper to model connectivity between HCAs. We developed this tool to support the 2010 Washington Wildlife Habitat Connectivity Working Group (WHCWG) statewide connectivity analysis, and are making it public for use in other wildlife connectivity assessments. The toolkit is available for download in a zip file that includes a user guide ,demo data, and scripts.
